#BTC #ARK The Ark Protocol @ArkLabsHQ has recently been updated with new progress, which is one of the off-chain protocols I pay attention to, many people may not know this protocol, I will make a brief introduction: 1. Ark is a protocol that uses the off-chain model to scale BTC 2. In the development of the Lightning Network, there are "channel capacity problems" and "scalability problems", etc., which cannot be solved in a short time, and Ark is another set of solutions envisaged on this basis 3. Since it is an off-chain solution, there must be a "on-chain and off-chain" module ▪️ On-chain, it leverages the concepts of "pre-signing" and "shared UTXO" to enable the ability to lock up funds and exit unilaterally, which is partly similar to @buildonspark ▪️ Off-chain, it has designed a virtual UTXO (VTXO) concept to replicate the model of a traditional UTXO ▪️ In terms of off-chain scalability, it uses script primitives to achieve more functions and achieve its goal of positioning "making BTC programmable". 4. In order to improve this problem, they introduced TEE to execute the operator to reduce trust dependence (this kind of trust is not the same as the trust of multi-signature, the operator cannot control the user's funds) 5. In terms of asset expansion, in its latest paper, it theoretically supports TA and most of its assets, but it has not yet been implemented 6. Because it is an off-chain expansion method, Ark and the Lightning Network can be partially combined, which can also be perceived from the fact that its asset protocol supports TA Finally, a little bit about the background of the Ark protocol: 1. This protocol has attracted the attention of many OG and BTC developers, such as linus, peter todd, Giacomo, and Adam Back 2. Seed round of 2.5M, led by Tim Draper and Draper Ventures -------- The second half of the 🫡 year is really getting more and more exciting
